[0002] A water pump is a machine that transports liquids or increases the pressure of liquids. It transfers the mechanical energy of the prime mover or other external energy to the liquid to increase the energy of the liquid. It is mainly used to transport liquids including water, oil, acid and alkali liquids, emulsions, suspensions and liquid metals, etc. It can also transport liquids, gas mixtures and liquids containing suspended solids.

[0003] In order to increase the flow rate and velocity of the water pump, the guide vanes of the water pump are generally increased. However, the increase of the guide vanes of the water pump will increase the length of the water pump and the flow rate and velocity that can be increased by adding the guide vanes inside the water pump are limited. It is necessary to design a new structure inside the water pump to accelerate the flow rate and velocity of the liquid. Summary of the invention

[0006] Furthermore, a primary guide vane is provided in the primary water trough, and the primary water trough is connected to the water inlet of the pump casing through the primary guide vane.

[0007] Furthermore, a secondary guide vane is provided in the secondary water flow trough, and the secondary water flow trough is connected with the primary water flow cavity through the secondary guide vane.

[0010] The beneficial effects of the present invention are:

[0011] The present invention sucks liquid from the outside of the water pump into the inside of the water pump through the first-level guide vane arranged in the first-level water trough, and the liquid enters the first-level water trough through the first-level guide vane, and then enters the first-level water cavity from the first-level water trough through the first-level water guide hole. After the liquid enters the first-level water cavity, the liquid is accelerated for a second time through the second-level guide vane arranged at the connection between the first-level water cavity and the second-level water trough, and the liquid flows out of the second-level water guide hole into the second-level water cavity and then discharged from the water pump. The liquid is accelerated for a second time through the liquid guide device arranged in the water pump, and because the liquid is compressed to a certain extent after entering the first-level water cavity due to the limited volume in the cavity, the liquid is accelerated for a second time.
